Characteristics

Designed for handling FPD substrate in a PFD production line or inspection line.
Telescope type is available for 760mm or longer Z-axis, which allows the low-passline.
Execution of origin search is not required by using the servo motors with absolute encoders.

Arm lineup: 400mm, 500mm
Twin-arm reduces the tact time.
Base or flange mounting type is selectable.
RS232C and parallel photo I/O are standard for control.
AC servo motors with absolute encoders installed in all axes.
High-speed, high-accuracy glass handling by S-curved speed control.
Wafer holding: end-effector with vacuum suction, passive edge, edge grip, or Bernoulli type End-effector
End-effector material: CFRP, Al, ceramic, or others.
Sensors (for alignment, substrate existence detection, mapping) can be installed in the end-effector.
Optimal end-effector is selectable according to the carrying object and line layout.

Standard Specifications

Representative specifications of LTHR4400C-600-AM.
It can be changed depending on the carrying object and end-effector type.
